Im building a flashlight and i want to test if a fan in it would be a good idea but the flashlight is really small so i would need a motor thats smaller than 1 cm preferably. I found really good ones at maxon group but unless you order them in bulk(1000+ units) they cost like 400€. So do yall know anywhere i could find them? Thanks in advance! (Edit: Im a complete baffoon and forgot to specify that preferably i would need a water resistant fan. I assumed this because bldc motors without drivers are wter resistant)

If you want a fan, why not buy a whole assembled fan? There are 10mm and 15mm fans available.

Im surprised they make fans this small but i think they are really weak. Im gonna order one of them to test the airflow but i wanted to make my own one to fit more fan in a package thats good for my light. But thanks anyway im gonna try some of these. If the performance is really bad, a custom built one probably wouldnt be much better.
